【摘要】: 黑洞長(zhǎng)久以來是理論物理學(xué)界感興趣的問題,并在最近取得了一些天文學(xué)上的觀察證據(jù)。黑洞的量子理論帶來了很多佯謬,如何去解決這些佯謬是極重要的,問題的解答將加深我們對(duì)量子引力的理解。弦理論是量子引力的一個(gè)備選方案,其中是沒有自由參數(shù)的,應(yīng)該可以解決佯謬。如何應(yīng)用弦理論來處理黑洞也是一個(gè)重要的課題。 我們要討論的是一類NS1-P黑洞的熵的問題。Bekenstein熵為Sbek=A/4G。如果我們不打算破壞熱力學(xué)第二定律,那么這個(gè)式子對(duì)黑洞就是成立的。這是我們的出發(fā)點(diǎn)。 ⅡB/ⅡA型超弦理論的低能有效作用量是ⅡB/ⅡA型超引力。在本文中我們要討論的黑洞是超引力的解。我們先對(duì)超弦,超引力,T對(duì)偶,S對(duì)偶Kaluza-Klein約化做一些介紹。因?yàn)槲覀冎粚?duì)玻色解感興趣,所以我們也只討論玻色解。我們希望找出一類NS1-P黑洞的熵并給出其物理上的解釋。 首先我們研究一下S對(duì)偶,通過S對(duì)偶我們可以給出NSl-P系統(tǒng)與D1-P系統(tǒng)作用量是等價(jià)的。NS1-P黑洞是NS1超引力的低能有效作用量的解。于是我們可以的知NS1-P黑洞和D1-P黑洞是等價(jià)的。而熵在S對(duì)偶下是不發(fā)生改變的。如果我們能解出NS1-P黑洞的熵那么我們也就知道了與之對(duì)偶的D1-P黑洞的熵。我們嘗試通過約化IIB 10維NS1-P系統(tǒng)來得到5維黑洞。并將弦標(biāo)架轉(zhuǎn)為Einstein標(biāo)架來求黑洞的熵。我們知道在弦理論中動(dòng)量和荷存在著等價(jià)性,通過計(jì)算我們期望能得出NS1-P系統(tǒng)熵和荷之間的關(guān)系。
